Indeed. That does not negate its base value even in barter. (Though it's much lower.) And especially items made with the use of gold can get really worthwhile

Indeed. That does not negate its base value even in barter. (Though it's much lower.) And especially items made with the use of gold can get really worthwhile - such as semiconductor chips... So in a funny indirect way, Bitcoin is tied to gold. Both of which are tied to specific costs of labour. Bitcoin however requires a lot of expensive infrastructure to run to be worth anything. (Esp. networking, required to ensure no fake mined bitcoins are in circulation.) Even printed cash is better at this.
